Haemophilia is a X linked genetic disorder. Males have one X and one Y allosomal chromosome while females have two X allosomal chromosomes. If a woman is a carrier then she has one dominant trait to cover the haemophilic recessive trait while in males it is the opposite, i.e., they do not have a dominant trait to cover the recessive trait if it is present on the X chromosome hence they are more prone to haemophilia than females. Thus, it is a very rare case of the possibility of haemophilic females, since it requires both the traits to be recessive in the female allolosome chromosomes.
